Microsoft is due to release a Technical Preview of Office 2010 to trusted partners and lucky registered testers in July, but in what's become a pretty common pattern, BitTorrent-savvy browsers are already seeing leaked builds.

We've seen screenshots from Office 2010 before, and bleeding-edge downloaders are seeing that, while Build 14.0.4006.1010 may or may not be the official Technical Preview package, it seems to be a reliably work-able package.

Ars Technica has a full set of Office 2010 Technical Preview screenshots, covering the installation, taskbars, and basic use of every app inside the Office package. What really has us excited, however, is Robert McLaws' screenshot of Windows 7 taskbar integration (partially pictured at right), which shows individual Office apps each getting their own taskbar slot, but also offering new message/appointment/contact/task creation and jump-to shortcuts from each icon. If you're the type to drop bleeding-edge office builds onto your system, note that both 32- and 64-bit builds are apparently out there. [via All about Microsoft]
